Upgrading from native MPIO to SDDPCM AIX 6.1

We have AIX 6.1 system attached to SAN disks (DS4700 and DS8100) thru SVC.

Initially when the system was I forgot to install sddpcm drivers. and wanted to know how can i go with the installation of the sddpcm drivers.

My understandin going thru the manual
http://publib.boulder.ibm.com/infoce...c/f2bsdu03.pdf

is

1. Unmount all the FS related to the VG.
2. varyoff VG
3. Export VG
4. rmdev -Rdl hdiskxx
5. install sddpcm drivers
6. import vg

Does this look correct.
